Pioneer MVNO · first plans for hearing-impaired
Created in 1999, former Vodafone subsidiary Coriolis was one of the first MVNOs (Mobile virtual network operator) in France. A pioneer in the French communications market, Coriolis created the Telephone Store network of mobile phone stores. With over 200 boutiques across the country, it is one of the largest mobile phone distributors in France.
In 2008 Coriolis became the first operator to offer plans for the deaf and hearing-impaired (2 hours video calling + data). The operator started offering Internet (ADSL) packages in October 2012 (which rely on SFR's network), and as of September 2015 offer a fiber optic Internet package in the Calvados region.

Coriolis: long-established MVNO with 200+ boutiques, but better value can be found on the same SFR network
Coriolis is one of France's oldest MVNOs (founded 1999), with over 200 Telephone Store boutiques offering face-to-face support — a real advantage for expats who prefer not to manage everything online. It runs on SFR's 4G/5G network, providing reliable nationwide coverage. The main drawback is pricing: Coriolis is less competitive than RED by SFR on the same network. Its hearing-impaired mobile plans remain a genuine speciality. For most expats, RED by SFR or Lebara Mobile offer better value on comparable coverage.
What we love
- 200+ Telephone Store boutiques for in-person subscription and support.
- Pioneer of hearing-impaired mobile plans in France since 2008.
- Runs on SFR's 4G/5G network: reliable nationwide coverage.
- Founded 1999 — one of France's most established alternative operators.
Keep in mind
- No English-speaking customer service.
- Less competitive pricing than RED by SFR on the same SFR network.
- Online account management is in French only.
- No dedicated English-language resources for expats.
What customers actually say
Coriolis's Trustpilot split is bimodal — two clearly separate groups of reviewers, with very little in between:
Trustpilot star split, August 2026
👍 Praised most
👎 Criticised most
“Even though I waited over 8 minutes, the young woman who answered was very competent, precise and patient — exactly what I needed. Thank you!”
Nathalie · 3 Aug 2026
“I really regret subscribing with Coriolis — I call to say the connection isn't working, and they just tell me everything looks fine on their end.”
Diaby · 12 Aug 2026
Read this split with the usual caution, but note what's distinctive here. Customers are still more likely to leave a review after a bad experience than a good one, a bias common to every platform. What stands out on this profile is how consistently the positive reviews are short, specific thank-yous to a named phone advisor for resolving a request quickly — while the negative reviews cluster around network/line issues that support couldn't (or wouldn't) acknowledge, and difficulty cancelling. Coriolis has responded to only 12% of negative reviews, well below Bouygues or Sosh, which may explain why unresolved complaints read as more bitter here.
